It would have been a very nice day at the beach for Leslie, if not for the fact that the waves crashing against the shore weren’t the only ones on her mind at the moment.

She and her friends had gone out not so much to have a good time as to prove a point; this was just the latest in a series of “experiments” to see if Leslie really was as strong as she kept insisting she was. Somehow, most of them ended up being Alexis’s ideas alone, but it was already well-established that just having come up with it wouldn’t be enough to give her an advantage over Leslie; and it had been proven equally well that she would need to be handicapped somehow if her friends were to outlast her.

Today, the public, outdoor setting was enough of an impairment on its own, but just to be sure, Taylor and Alexis had taken it upon themselves to bring some extra-large drinks along for Leslie. Of course, she had been all to glad to fill herself up, and now she was definitely feeling the consequences.

Not like that meant very much, though – the other two girls on either side of her were already squirming, if only a little bit, but Leslie was able to sit still on her towel, her legs folded and hands on the ground behind her as she leaned slightly back. Sure, she very much needed to pee, but there was no need to make a show of it; and all her sweat and her red face could easily be attributed to the heat.

And, technically, there was nothing stopping her – or any of them, for that matter – from just getting into the water and acting like anyone else would with the bathrooms in such an inconvenient location. But Leslie had teased her friends about relieving themselves outside like that enough that there was no way she could do it herself; and the others were too intent on beating Leslie.

That really had been a lot to drink, though, and Leslie’s shorts were starting to feel a little tight around the waist. The absence of any covering beyond a bikini top for her torso made it obvious why – her lower belly was ever-so-slightly distended and pressing up against her clothing. Nothing she hadn’t dealt with before, though.

“Don’t you just love listening to the ocean?” Alexis leaned in to speak with a quiet, teasing voice. “The splashing and hissing is all just so relaxing, isn’t it?”

“Haven’t you got anything better to do?” Leslie didn’t look over at her.

With a malevolent chuckle, Alexis replied, “Actually, now that you mention it… It’s been a while since our last drink, hasn’t it?” She crawled over to the cooler they had brought, opening it up and pulling out three bottles of peach tea, one conspicuously larger than the others. Alexis handed that one over to Leslie. “Drink up,” she said. “It’s really hot today, after all. Gotta stay hydrated, y’know?”

“Right…” Leslie rolled her eyes and took the bottle, taking a few big sips as soon as she took the cap off.

“Hey, Lexi,” Taylor said as she reached out behind Leslie to grab the drink Alexis was offering. “That’s her third one of those so far, isn’t it?”

“Oh, yeah.” Alexis moved in even closer to Leslie, leaning on her shoulder. “Bet your bladder’s all nice and full, hm? Just like the last time you had three of those bad boys, right? You’re even wearing the same shorts.”

Leslie glared quietly at Alexis, still working on her drink just to get it out of the way.

“You do remember how that turned out, don’t you? You swore up and down that you could hold it,” Alexis continued with her taunting tone. “Hold it like an adult, you said, but then… Oh, you couldn’t even last until the third hour before you peed all over the chair through those shorts.”

Taylor looked over and adjusted her position as she took little sips of her own drink. “Think she’ll last longer this time? It’s already been… jeez, two hours since she started drinking.”

“I dunno. What do you think, Leslie? You gonna hold it this time?” Alexis sat back and took a swig of her tea, making sure the contents of the bottle would swirl around as much as possible. “Or are you gonna wet those shorts again? Y’know, feel all that pressure just fade away as all that hot, pent-up pee finally gets to flow out and soak your clothes, and make a nice big puddle right here on the sand? Wouldn’t that be nice?”

“That’s… not going to happen,” Leslie said, her voice wavering for only a moment. “Maybe you two are gonna piss your swimsuits or find somewhere to squat in the sand like it’s your litterbox, or something, but I’m gonna hold it.”

“Oh yeah? Until when?”

“I don’t know. Until the two of you have gone off and wet yourselves somewhere, and then maybe a while after that, I suppose.”

Alexis laughed at the response, and Taylor joined in with a chuckle of her own. “You really think so?” Alexis took another sip of her tea once she calmed down. “It’s been quite a while, and you’ve had a lot to drink… Your bladder’s getting all big and round, too. Bet it feels really heavy, like you’ve got a bowling ball in there pressing down and so ready to come out, right?”

Leslie’s response was a quiet groan as she set aside her empty bottle, finally changing position to sit on her heel with her hands on her knees.

“Oh, what’s the matter? Can’t sit still without a bit of pressure?” Alexis leaned over and took a few jabs at Leslie’s belly. “This little balloon’s gonna pop, isn’t it?”

“A-ah… Stop that…”

“Why? I thought you could hold it.”

With a quiet growl, Leslie suddenly reached out with one hand and pressed hard against Alexis in the same spot as where she was poking Leslie. Alexis’s eyes went wide in response, and she gasped as she squeezed her thighs together and slipped both hands between them.

“Y-you fucking…”

“What? It’s… fair, isn’t it?” Leslie risked laughing despite the immense pressure within, stopping after a moment and digging her fingers into her thighs. “Didn’t wet yourself, did you?”

“Of course not!” Alexis took a deep breath, then picked up her half-drained tea. “But I’m sure you’re going to soon,” she said as she started swirling and shaking the bottle. “I-I mean, isn’t this just like what’s going on inside you right now? All that pee sloshing around until…” She stopped moving the bottle to remove the cap, then tip it over just enough to let some tea trickle out onto the sand. With an evil giggle, she added, “Whoops. Looks like I spilled a little bit.”

“Come on,” Taylor said while Alexis took a sip and closed her bottle again. “Don’t tell me you’re not looking forward to getting to a bathroom so you can sit down and let loose. Why not cut out all the waiting and walking and just do it right here? I know you want to.”

“I-I don’t.”

“You need to,” Alexis commented. “You’re all bloated and full, and your dam’s breaking.”

Taylor pulled her phone from her bag and pointed it at Leslie to start recording video. “Why don’t you just get in the water before you embarrass yourself?”

“All part of the water cycle, after all,” Alexis added.

“Or maybe you’d rather just leave a huge puddle on your towel. I mean, they are supposed to get wet, right?”

“Wouldn’t that be nice? You could make a little ocean of your own right here.”

“With a waterfall and river rushing into it…”

“When all your squirming and wiggling isn’t enough, and the pressure’s just too much for your poor, tortured bladder to handle…”

“You’re gonna pop!”

“Just like a little girl, remember?”

Suddenly, Leslie spoke up, interrupting their back-and-forth. “Stop it!” She was still sitting with one foot beneath her, and both hands on her knees, but now her whole body was trembling. “Stop.” She groaned and took a few deep breaths, then moved to get herself off the towel and pull it over herself like a cloak. Kneeling in the sand with her body hidden from behind, she groaned again and fumbled with the button on her shorts, her trembling hands eventually undoing it and pulling the zipper down as well. Then she pulled her shorts and the swimwear beneath them down just far enough to be out of the way before bringing her rear end down as close to the sand as possible and giving up.

She was panting while the sand beneath her quickly grew dark, and soon enough started amassing a puddle as she added more fluids faster than they could be absorbed. Both of her friends were watching, but she didn’t seem to be paying them any mind.

“Told you,” Taylor said. “Like a big ol’ water balloon.”

“Aw, couldn’t hold it?” Alexis teased. “Had to use the ground instead of a toilet?”

Every breath a quick huff, Leslie looked over at Alexis. “My bladder’s still bigger than yours,” she said as she continued spraying down the sand just as fiercely as when she started.

“Sure doesn’t look like it.”

“I’ll prove it… in a fair contest.”

Alexis put a hand on her chin and wiggled her hips. “Hm, I don’t recall all your taunting being very fair… Besides, we already gave you a fair challenge and you lost.”

“And then it turned out just the same here,” Taylor added.

Leslie took a deep breath and looked back and forth between the two of them. “I will prove it,” she said.
